forward of which and spaced therefrom is a bulf Ywark Which inclines Y upwardly and Vrearwardly and is adapted to support the axles of an autom'c bile and which is provided with longitudinal passages adapted to receive at their front ends-'the wheels of the automobile. A

- The bulwark, in the form shown; comprises longitudinal upwardly and rearwardly inclined parallel bars 2, which may be angle bars, adapted to slidingly support the axles of a` transgre'ssing automobile, and spaced toform between them Vpasl sages adaptedto receive the'wheels of the au't'ome bile.

The forward ends of the bars 2 are fastened to a cross bar 3 of a rectangular frame 4 set in the pavement 5 with its upper side nush with the surfe face of the pavement. The rear end portions erallyextending angle'bars-Q fastened of thebars 2Vextend downwardly and arefasrelative Y lateral movement. r Between each pair of bars 2 are upwardly and rearv'vardly inclined bars 7, preferably of resilient material, as spring steel, which bars '7 converge v I rearwardly and are so spaced as to receive between them at their` front ends the wheels of an auto mobile, Yand tok engage and pinch between them in Fig. 5, thus serving to arrest the forwardinovement` of thewheels. As shown in Fig. 1, some the other bars 2 and 7, so that the outer sides of a pair of such diverging bars may engagethe inner sides ofthe front wheels forward. movement. f l i The front endsof the bars '7 are fastened to the bars 2 over the cross bar 3. The rear ends of the bars? are fastened to the cross bar 6. The barsf'serve as side wallsy for the passages receiving -the automobile wheels. n 1

Such means, as shown in Figs. 1 and 3, comprises rearwardly and latdiagonally uponthe base frame 4.*y j. e

Y

f AForward of the base frame 4 may be fastened to the pavement 5 usual tranicbuttons 11 arrangediri Arows forming a triangle, Figs. l and 6.` theapexbf whichisat the front. These traic lli) 4:ist

buttons may be some of them illuminated in the usual manner, and they form signalling means to a driver running upon them, to notify him that he is encroaching upon a safety zone, such signalling being by observing the lighted buttons, or by the jarring of the wheels. The buttons, as shown in Fig. 1 are disposed in their rear row so as to be respectively at the forward ends of the diagonal bars 9, sothat wheels passing between the buttons of the rear rowv will be guided between the bars 9, so as to be diverted laterally thereby.

A car approaching from the front inlalinement with the safety zone l will strike the buttons 1l, thus signalling the driver of Ythecar. If he does not laterally guide the car the wheels thereof will run between the bars 9 and will be laterally diverted thereby, or, if passing over the bars 9, the wheels will pass between two pairs'of the rearwardly converging bars '7, and the axles will ride upwardly on the inclined bars 2.

`'Ihe bars 7 will pinch the wheels ,engaged by them, which, with the upward inclination of the bars 2 will tend to stop the car` .If the car is not stopped before the front axle strikes the blocks 8, the latter will, in most. cases bring the car to a full stop. If the momentum of the car is sufcient to carry it past the blocks 8, due to the high rate of speed at which the car may `have been travelling, the wheels will .strike the cross bar 6, and in case that this bar does not stop the car, the wheels will strike the front end ofthe safety Zone platform l and will finally bring the car to a stop before it can pass onto the platform. By having the bars 2 inclining upwardly from their front ends at one angle only of inclination to the blocks 8, as shown, the friction of the bars against the axles of the car will be applied evenly and gradually thereto, thereby tending to bring the carto a standstill with a minimum of shoclrto the car and its occupants.`

In most instances, Vthe arresting means -described and shown will stop an encroaching car with little injury to the car and none to the occupants thereof, as well as protecting the occupants of the safety Zone from injury by the car.

Other modifications of my invention, within the scope of the appended claims, may be 'made without departing from the spirit of my invention.

What I claim is:-`

l. In a safety zone guard, a bulwark adapted to be placed at one end of a safety zone and 1inclining upwardly and rearwardly toward the Zone and adapted to slidingly support the axles of an automobile and provided with longitudinal passages adapted to receive therein at their front ends the wheels of the automobile, said passages having rearwardly converging side walls adapted to engage the sides of said wheels and arrest the rearward movement thereof.

2. In a safety zone guard, an upwardly and rearwardly inclined bulwark adapted to slidingly support the axles of an automobile, and provided near its rear end with abutment means adapted to engage and stop the forward movement of the front axle of the automobile, and provided Ywith longitudinal passages adapted to receive at their front ends the wheels of the automobile, said passages having rearwardly converging walls adapted to engage the sides of said wheels andarrest the forward movement thereon 3. In a safety zone guard, a bulwark adapted to be placed at one end of a safety zoneandhavto engage the sides of said wheels and arrest their forward movement.

4. In a safety zone guard, a bulwark adapted to be placed at one end of a safety zone and having longitudinal passages adapted to ,receive at vtheir front ends the wheels of an automobile and having rearwardly converging resilient side walls adapted to engage and exert a spring pressure against the sides of said wheels so as to re- `sist their forward movement.

"5.In a safety zone guard, an upwardly and `rearwardly inclined bulwark adapted to be placed at one end of a safety Zone and to slidingly support the axles of an automobile and provided with Alongitudinal passages adapted to receive at theirforward ends the wheels of said automobile, said passages having therein resilient means adapted to. exert a pressure against the sides of said wheels so as to resist their forward movement. l

6. In a safety zone guard, a bulwark adapted tobe placed .at one end of.a safety Zoneland tol wardly inclined bars adapted to be placed at one "z end 0f asafety zoneand to slidingly supportcthe axles of an automobile and spaced to form longitudinal passages `adapted to receive between them at their front ends the wheels ofthe automobile, and longitudinal Ybars disposed in VVpairs the bars of each pair converging rearwardlyin said passages and adapted each pair to engage the sides of ,one vof said wheels so as `to arrest its forward movement.

8. In a safetyzone guard, upwardly and rearwardly inclined longitudinal .bars adapted to -be placed at one end of a safety zone and to slidingly support the axles of an automobile and spaced to form passages betweenrthemadapted to receive at theirfront ends the wheels of the automobile, two of said bars diverging vrearwardlyfromeach other and being so spaced as to adapt them to so .engage the sides of said wheels asto arrest their forward movement.

9. In a safety Zone guard, longitudinal upwardly and lrearwardly inclined-bars spaced to form longitudinal passages adapted to -receive the vwheels' of Aan automobile, said bars being adapted to slidingly support the axles of the automobile, and means connecting said bars adjacent to their rear ends for holding their upper portions from relative lateral movement.

10. In a safety yzone guard, the combination with a safety zone, of longitudinal upwardly and rearwardly inclined bars yspaced to form between them passages adapted to receive the wheels of an automobile, and adapted to slid- .ingly support the axles of the automobile, said bars extending from their front ends at one angle ,of inclination only to substantially their `uppermost parts.
